I'm going to be a pedant and say that I referred to 'offensive language' i.e. Yuppy Flu and the inference that Chronic Fatigue isn't real. Maybe I just read it wrong or I'm very wary about terminology. Maybe I'm over-thinking what you wrote and I'm sensitive re. this subject due to personal circumstances. I don't know.
I'm not offended. There is a difference between being 'aware' that something is offensive and being offended.
I do not see references to 'Yuppy Flu' in any of my source material. I've only ever seen that term on this board. It's a derogatory term for Chronic Fatigue. No difference in using the term spaz or flid for example.
